for burglar proof chests adapted to hold the" collections made at theindividual stores, the-' aters and stations,,which chests or safes, as

they areirequired in large numbers by thevarious individualorganizations, must to meet this demand, be manufactured andsold at arelatively small cost, and they further must for this trade be soconstructed as to enable the proprietors to obtain insurance atpreferential rates. The chestsprovided at present for this puropse arenot satisfactory in that when constructed to meet the requirements theyare-too expensive. I The doors and the labor required to fit and mountthe same, and particularly thehinges, are a considerable itemof expense.

The present invention relates to a chest and to a door structure anddetails for mounting and securingthesame whereby: the use of hinges isavoided andthe maximum of security and convenience is obtained-at theminimum of expense, the structure being one which can be produced: inlarge quantities much more cheaply than any chest prevlously offeredwhich is adapted to the same general purposes, -The invention furtherprovides for the normal retention of thedoor in mounted position withoutdanger of accidental release and forthe convenient removal of thedoorwhen open and it may providedouble custody where it is founddesirable, there be v ing for this purpose an mner compartment soarranged that while it ispartially accessible to the employees of thelndiv dual stores or I stations who are acquainted with the combinationin order that they may depositthe money as collected, which is usuallymade into packages and introduced through a slot organization whocarries thekey for this s purpose;

Instead of a; single inner compartment guarded byan inner door, theinner door may be so arranged as to provide beyond the chest the top ofthe safe flIlCluEL with" the door removed.

Referring to the drawings by numerals, each of which is used to indicatethe same or similar parts in the different figures, the constructionshown comprises a chest body 1, which may be of any preferred orconvenient shape and provided with ears 2, by which it may be anchoredin a suitable concrete structure or secured within a safe or similarenclosure in accordance with the prevailing practice. In order to obtainthe benefits of the preferential insurance rates, the walls of the chestbody should be made at least an inch thickof any suitable steel or steelalloy used for this purpose. The chest as shown is provided with a chestdoor opening 3, near the front end and spaced inwardly therefrom asshown, the opening 3 being shown as substantially semi-circular andslightly less than half the area of the chest door 4 and the door jambopening to be hereinafter described. As shown, opening 3 occupies theupper half of the cross section of the chest being spaced slightly abovethe centerwith its straight side at the bottom of the opening. The chestdoor or main door 4 is of circular outline'and preferably of one and onehalf inches or more in thickness throughout its area to comply with therequirements for the above mentioned preferentialinsurance rates. Thismain or chest door 4 is without hinges or similar supportin means, beingmounted to rotate in a circu or door jamb or seat 5 of correspondingsize located outside the door opening 3 and within the end or end edgeof the chest body 1.

The door may be rotatively secured in any suitable manner preferably thedoor jamb or seat 5 is formed with. an" annular inwardly disposed roove7, the outer wall of which consists o a likewise inwardly disposedannular rib 8 and the door is formed as to its outer edge with aperipheral groove 9, which receives the rib 8, and the door is likewiseprovided with a peripheral outwardly projecting; rib 10, forming theinner wall of groove 9-which rib engages and follows the groove 7 in thejamb or seat. The door 4 is supported and guided-mainly in and bycircular-or short cylindrical seating surface 61 forming the outerportion of amb 5. This surface is closely engaged by a correspond- 'ingcylindrical surface 62 on thedoor which guides and supports the door,said surfaces being finished concentrically. The ribs 8 and ferred to asthe inter-engaging members or ribs, are each. of them interrupted ordiscontinued at intervals, so that the door being in closed position inwhich it may be locked, it may, having been duly unlocked,'be rotated tofull open position and the stop to be described being released, be thenfurther rotated in the same direction to a position in which the arcuateportions of the rib 10 to be further described, overlie the spacesbetween the portions of the rib 8,permitting the door to be removed andreplaced.

To provide for opening the door, the door or door member 4 is formedwith an aperture 12 which is preferably. semi-circular in outline asshown and adapted. to register with door opening 3, being similarlyshaped and located relatively to the center of seat 5 about which thedoor 4 rotates when mounted in the chest. The aperture 12 is shown as ofa size somewhat less than half the area of the door 4 so that itsarcuate edge 13 is conveniently spaced inwardly from the edge of thedoor providing a suitable marginal portion 14 to support the ribv 10 orthe arcuate sections thereof to be described. The flat side 15 or otherportion of the aperture 12 in the door .I

4 which is nearest t-hecenter is also preferably, spaced outwardly fromthe center of the jamb 5 and of the door. This opening 12 is thuspractically of the same size as the door opening 3 and to, open the doormounted as described it is rotated to bring the opening 12 in the doorinto registration with the door opening 3, see Figure 12. To close thedoor it is rotated 180 degrees from this position or through anysuitablearc depending on the 1 already described, the door jambseat 61conifi tains a. stop groove 16or the equivalent to be engaged by a stoppinl'T to limit the normal rotation of the door from open to closedposition and vice versa, the object of the stop mechanism being toprevent the door from,

becoming disengaged, otherwise than with the intent of the operator.Vhen, however,

' as already pointed out, it is desired to remove the dooror insert it,the stop pin 17 is withdrawn.

To provide for its normal engagement andv eral edge 18 of the door in ahole or guide 19 Which extends throughthe peripheral face of the door,is urged outwardly into engagement with groove 16 by a coil spring 20 inthehole behind thesliding pin or stop bolt 17 and the sliding pin orstop bolt '17 is provided with a laterally projecting lug or handle 21which slides in a bayonet slot 22 formed in the back of the door andextending into the hole or guide 19so that it is out of reach exceptwhen the chest door is Open; Thislug or handle 21 can be engaged by theoperator in snobvious manner when the door is open, the operatorreaching inside for this purpose and being thus engaged, the stop inl7'c'an be withdrawn and locked in withc rawn position by rotatingthepin or bolt 17 until the lug'or handle 21 moves into the -base24 of thebayonet or L shaped slot 22. When the stop pin or bolt 17 is thuswithdrawn, the door being opened and therefore essentially unlocked,

it can be rotated oppositely to the direction of closing beyond openposition to a position in which it is released and may be removed,

As already suggested, the" interlocking ribs 10 on the door and 8 on thedoor jambare discontinued or interrupted at intervals forming ribsections which interlock and hold the door in its seat in all positionsto which it can be rotated when the stop pin or bolt 'l7'is advancedengaging the groove 16. The

exact length spacing. and arrangement of the sections and the form ofthe interlocking means is capable of widevariations, apreferred,arrangementbeing illustrated in Figure 4, showing the door, and Figure 7showing the door opening in the chest, the door being removed, andFigures Sand 15,'show-' ing the door in position in the chest.

In accordance with the illustration, Figure 4, the riblOon the doorconsists of spaced arcuate outwardly projecting sections. At the top inthe closed position of the dooris the section 26 which is, relativelylong, comprising an arc of about 90 degrees, and proceeding around thedoor in' right handed ro tation as seen from the rear in Figure 4,.next

to the r1b28 is a space 27 which is about the ribs and Spaces Onfthedoor and door j same length as rib 26,.and next beyond this spaceis ashort rib 28.- Next is a space 29 a little shorter than this rib, andbeyond the space 29 is a rib 30 shown asa little shorter than the rib;28, next is a space 31 longer than rib 30. Following this is a rib'32about the length or" thespace 31 and beyond this is a space 33 of alittle less,thanthe length of' rib 26. While the spacingin the formpofthe invention shown has been described, the exact spacingof the ribs and'their length is immaterial'otherwise than as it contributes to theresultand object which is to hold the ,f

door and permit it to be rotated from open to closed position and viceversa, and to permit projecting rib 8 on the door jamb comprises in thepreferred formof the invention as shown the following arcuate sectionssuitably spaced, i. e.,,at the top is a long section 35 of the rib 8comprising an arc-of a length a little less than the length of the space27 on the door, and proceedingin right handed rotation as the chest isseen in Figure 8, this is followed by a space 36 a little longer thanthe rib 26 on the door, following which space is a rib 37 a'littleshorter than the space 33 on:

the door; Beyond this rib 37 is 'a space 38a little. widerthan the rib32 on the door and next beyond this space 38 is a short rib 39a littleshorter than'space 31 on the door. Beyond the rib 39 is a'space 40 alittle longer pass the rib 28 on the door. As pointed out regarding thesections of the rib 10 on the door, the spacing of the sections of therib 8 on the doorjamb maybe widely varied, and

is only material to the result that the door be held against removal inclosed position and in normal openiposition and throughout the path ofrotation from one positionto the other. Inthe form shown therotation-ofthe door is normally limited to this path or a slightlylonger one by means of the removable;

than rib 30 on the door. Beyond this space 10 is a rib 11 a littleshorter than space 29 on. the door and between the rib 4:1 and the toprib 35is a space l2 which, is long enough to stop latch 17, but this maybe omittedorthe result otherwise accomplished within the scope of theinvention, the door being preferably capableof rotation when the stoplatch is released, to. a position in which the sections of the rib 10on'the door are thrown'out, of

contact with the sections of. the rib Son the" 'jamb and intoregistration with the spaces between said ribbed sections whereby thedoor may be removed, or when. presented in the same angularposition maybe inserted. In the construction shown the position of registrationisindicated by the comparison of the contained in the description of thedoor j amb Y To reach position? clockwise from the closed position,Figure 8, a

to full open position and the stop 17 having been withdrawn, the door isfurther rotated in the same direction until space 27 on the doorregisters with rib section 35 at the top of the door j amb, see Figure15. In this position the rib sections on each-member register withthe-spaces onthe other, permitting the" removal and replacement of thedooras aforesaid.

In addition-to the stop pin 17, the door is provided with a bolt whichslides outwardly beyond the periphery of the door and is controlled'byany suitable lock 46 shown as ofthe combinationtype. The outer end ofthe-bolt 4-5 in locked position occupies a keeper slot 47 in the doorjamb. There .is also a second slot 49 to be engaged by the Jolt in thepartly open position, Figure 10, in which position the combination ofthe lock canbe changed by means of a pin placed in slot ll), Hole 49 isalso utilized in this connecton. In this position of the door the stop17 can conveniently be reached and withdrawn. The door is also shown asprovided with handles or hand grips 4-8.

. The locking bolt 45, the lock 46 and the stop 17 are in the preferredform of the invention shown located in the semicircular half of the doorwhich is at the top in the closed position of Figure 1. This portion ofthe door overlies a semicircular depression 65 in the rear face of thedoor and forms the outerwall or base of the same, the exact shape of thedepression not being of great importance. By means of th s depressionthe stop member 17 is made easily accessible from the rear while theslot 16 which it engages is near the front. The depression also providesroom for the lock 46 without reducing the capacity of the chest andkeeps the entire area of the door of the desired normal thickness,avoiding unoue weight and expenditure of material, and allows amplethickness at the edges to accommodate the rib 10, the groove Eland the.cylindrical seating surface 62 at the front.

The dcprcssiou65 is closed at the side which is at the bottom in theposition stated by the d ametrical wall or thickened portion 64-, whichhas its rear surface in the rear radial plane or finished rear surface80 ofthe door Which contacts the forwardly disposed rearmost surface 81of the jamb, sealing the periphery of the opening 3 at all points in gasthe closed positon, Figure 1.

In the conduct of chain stores and oil stations. it is desirableto havethe chestor safe so arranged that the collections may be deposited. ineach individual safe by the employees of the store in which it islocated, the employees being. however, harredfroin access tothe safe ina manner which would enable them to remove the contents. the money beingsubsequently removed by an employee who acts as collector for theorganization and has sole access to the contents of the safes of theentire cha n or a considerable portion of it for this purpose. To thisend, the present structure be provi with a second or inner door 50 whichclo s one door opening 3 inside the main or chest door. the inner door50 being held in closed position by a su table typeof key lock 51 towhich the collector referred to will carry the key and by suitabletenons 59 fitting in slots 60. This door in the form of the inventionshown is semi-circular, fitting the door opening 3 which is finishedwith a peripheral seat 52 to receive the door, the seat being slotted atthe bottom to admit any suitable tongues or projections or edge portions53 at the bottom of the door, the door being then swung into positionand secured by means of the lock 51. This lock is shown as having a bolt54 which enters a keeper 55'formed in or secured to the body of thechest wall. To provide for the deposit inthe safeof the money ascollected, the inner door 50 is slotted at 56 or the safe may beprovided with achute 57 for the admission to the inner compartment 58 ofenvelopes or packages of money or other valuables. This latter is inaccordance with the practice in moving picture houses in which the safeis placed below the ticket window so that the money can be packaged anddropped into the safe as and when a sufficient quantity is collected.

In Figures 13 and 14 I have shown a slightly modified constructionproviding for double custody, the inner door 66 in this instance be ngarranged horizontally and opposite or slightly below the bottom of thechest door opening 3, the inner door 66 with its frame 67 and thesupporting lip therefor 68, which is formed on the inside of the chestbody 1, for this purpose, comprising a horizontal partition whichdivides the inside of the chest into an upper chamber 69, which isimmediately accessible through the door opening 3 and a lower chamber 7O, which is accessible only from the upper chamber 69 by way of theinner door 66, or, more properly, the inner door opening 71, which isclosed thereby. The inner door 66 is shown as provided with a slot 7 2for the admission of envelopes, and similar packages of money and thelike and is secured in an suitable manner as by means of a lock73 wich'is preferably of the key type, having a bolt 7 4, which enters asuitable keeper slot 75 at one side of the door jamb or groove 76 in theframe 67 in which the door rests, the door having at the other side asuitable tongue or tenon 7 7 which enters a corresponding slot 78 in.the door frame.

-The manner of using and operating the chest and particularly the chestdoor has been quite fully explained in connection with the.descriptionof the structure. Assuming that the chest door4 has beenremoved and is to be placed in position, it is engaged by the handles 48and inserted in the jamb 5, being rotated to the position in which thesections of'the rib 10 on the door register with the ,spaeesbetween thesections-of the rib 8 on the jamb asindicated in Figure 15. In thisposition the stop 17 i and the bolt 45 being withdrawmthe stop pin 17being held in withdrawn positionby inserting the lug 21 thereon passthesections of the rib 8 in the j amb and enter the groove 7 in the jambwhen the door can best be rotated to the position shown in Figure'lO,.in which position the stop or stop pin lTmay be released and allowed toenter the-stop groove 16 Thebolt 45 may be caused to enter the slot 49as a'c0nvenient means for locating the doorin' this position. \Vhen thestop 1'? has been released and allowed to move by expansion of thespring 20, to operative position, the bolt 45 being withdrawn, the doormaybe rotated to closed or to full openposition to suit the Iconvenience of the operator, being'locked in closed position bythe-entrance of the bolt 45 into the keeper slot47', the door opening I'3 bei'ngpreferably eccentric as to the jamb and door and the aperture12 in the door being likewise preferably eccentric as shown. TheopeningB is uncovered and the chest is opened by rotating the door toaposition in which the opening 3 and aperture 12 are in registration andthe chest door is closed by rotating to place the aperture 12 completelyout of registration and out of alignment at all points with the opening3. To give the desired protection for the contents of the safe and toavoid cracks and openings between the door and the door jamb, whichwould be a source of weakness in case of an attempt-to crackthe safe,the surfaces of the grooves and ribs 7, 8, 9 and 110 are preferablyfinished and suitably fitted likewise the cylindrical outer surfaces61-62 of the jamb and door, the rear surface of the door and theforwardly disposed rear surface 81 of the door ja'mb providing a closefit as to the meeting surfaces 'which contributes to the closing andguardingof the door opening 3 in the closed-positionof the safe. The useof the inner door 50, Figure 1, permitting the insertion of envelopes orsimilar packages of moneyor the like through the slot 56 to be retainedin. the safe, said packagesbeing only accessible to, the'person,presumably the authorized agent of the owner, having possession of thekey, the lock 51 being shown as a key lock, though any suitable lock maybe used within the scope of theinven- 'tion, has been fully explained.The door is shown asanchored to prevent removal from thesafe by means ofa chain 83.

The use of the construction, Figures 13 and 14,'is similar except thatthe contents of the upper chamber ,69 is accessibleto all those havingaccess to the safe for any purpose while the lower compartment intowhich packages and envelopes may be introducedby wayof aslot 72 isclosed by a separate lock, usually a key lock, so that the contents fromreaching may be handled by a collector-or other per- 7 son dulyauthorized I have thus described specifically and, in
